Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. We find that annual material resource production places tight limits on Li-ion, VRB and PHS development and loose limits on NaS and CAES.

Pike Research: total capacity of worldwide spinning reserves for the grid to increase 40% by 2022

Green Car Congress

By 2022, natural gas and coal plants will still account for 93% of total spinning reserves capacity, but energy storage will grow to 7% of capacity in the same time frame, according to the report. Of particular interest to grid operators are advances in battery technology, particularly lithium-ion (Li-ion) batteries.

Georgia Tech life-cycle study finds TCO of medium-duty electric and diesel delivery trucks similar; electric life-cycle energy use and GHG lower than diesel

Green Car Congress

They also found that the total costs of ownership (TCO) of the electric and diesel trucks are similar. Battery replacement is another key factor; to maximize the benefits from electric trucks, the durability and reliability of the automotive Li-ion battery are crucial, which might be advanced with technological development.

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

Electrofuels approaches will use organisms able to extract energy from other sources, such as solar-derived electricity or hydrogen or earth-abundant metal ions. Li-S Battery : Development of High Energy Li-S Cells for Electric Vehicles. This process is less than 1% efficient at converting sunlight to stored chemical energy.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. Addition of up to 50 mol% Na 2 CO 3 to a Li 2 CO 3 electrolyte decreases electrolyte costs and improves conditions for intercalation in Na-ion CNT anodes. Addition of BaCO 3 increases electrolyte density.

California Air Resources Board Pushes for Restoration of DOE Funding for Hydrogen Fuel Cell Vehicles; Tackles the Four Miracles

Green Car Congress

Fuel cell system durability has improved and costs have been reduced through R&D, the ARB staff noted. In volume production, FCVs are expected to be cost competitive with other advanced vehicles, and are approaching the cost of advanced hybrid system even with current designs and high costs of materials.

New Trends in The Designing of EV Batteries

Get Electric Vehicle

The lithium-ion cell (li-ion cell) is the most popular chemical in the EV sector. Two electrodes, one positive and one negative are sandwiched around an organic (carbon-containing) liquid to make up a lithium-ion battery. The inadequacy of lithium-ion batteries for usage in automobiles is another issue.
